Install YugabyteDB Anywhere software - Kubernetes

Install YugabyteDB Anywhere on a Kubernetes Cluster

You install YugabyteDB Anywhere on a Kubernetes cluster as follows:

Create a namespace by executing the following kubectl create namespace command:
```
kubectl create namespace yb-platform
```
Apply the YugabyteDB Anywhere secret that you obtained from Yugabyte by running the following kubectl create command:
```
kubectl create -f yugabyte-k8s-secret.yml -n yb-platform
```
Expect the following output notifying you that the secret was created:
```
secret/yugabyte-k8s-pull-secret created
```

Run the following helm repo add command to clone the YugabyteDB charts repository:

helm repo add yugabytedb https://charts.yugabyte.com

A message similar to the following should appear:

"yugabytedb" has been added to your repositories

To search for the available chart version, run the following command:

helm search repo yugabytedb/yugaware --version 2.13.2

The latest Helm chart version and application version is displayed via the output similar to the following:

NAME                 CHART VERSION  APP VERSION  DESCRIPTION
yugabytedb/yugaware 2.13.2          2.13.2.0-b135  YugaWare is YugaByte Database's Orchestration a...

Run the following helm install command to install the YugabyteDB Anywhere (yugaware) Helm chart:
```
helm install yw-test yugabytedb/yugaware --version 2.13.2 -n yb-platform --wait
```

Optionally, set the TLS version for Nginx frontend by using ssl_protocols operational directive in the Helm installation, as follows:

helm install yw-test yugabytedb/yugaware --version 2.13.2 -n yb-platform --wait --set tls.sslProtocols="TLSv1.2"

In addition, you may provide a custom TLS certificate in the Helm chart, as follows:

helm install yw-test yugabytedb/yugaware --version 2.13.2 -n yb-platform --wait --set tls.sslProtocols="TLSv1.2" tls.certificate="LS0tLS1CRUdJTiBDRVJUSUZJQ..." tls.key="LS0tLS1CRUdJTiBQUklWQVRFIEtFWS0t..."

where certificate and key are set to full string values of your custom certificate and its corresponding key.

Use the following command to check the service:

kubectl get svc -n yb-platform

The following output should appear:

NAME                  TYPE           CLUSTER-IP     EXTERNAL-IP    PORT(S)                       AGE
yw-test-yugaware-ui   LoadBalancer   10.111.241.9   34.93.169.64   80:32006/TCP,9090:30691/TCP   2m12s

Use the following command to check that all the pods have been initialized and are running:
```
kubectl get pods -n yb-platform
```
The following output should appear:
```
NAME                 READY   STATUS    RESTARTS   AGE
yw-test-yugaware-0   4/4     Running   0          12s
```
Note that even though the preceding output indicates that the yw-test-yugaware-0 pod is running, it does not mean that YugabyteDB Anywhere is ready to accept your queries. If you open localhost:80 and see an error (such as 502), it means that yugaware is still being initialized. You can check readiness of yugaware by executing the following command:
```
kubectl logs --follow -n yb-platform yw-test-yugaware-0 yugaware
```
And output similar to the following would confirm that there are no errors and that the server is running:
```
[info] AkkaHttpServer.scala:447 [main] Listening for HTTP on /0.0.0.0:9000
```
If YugabyteDB Anywhere fails to start for the first time, verify that your system meets the installation requirements, as per Prepare the Kubernetes environment.

Customize YugabyteDB Anywhere

You can customize YugabyteDB Anywhere on a Kubernetes cluster in a number of ways, such as the following:

You can change CPU and memory resources by executing a command similar to the following:

helm install yw-test yugabytedb/yugaware -n yb-platform \
  --version 2.13.2 \
  --set yugaware.resources.requests.cpu=2 \
  --set yugaware.resources.requests.memory=4Gi \
  --set yugaware.resources.limits.cpu=2 \
  --set yugaware.resources.limits.memory=4Gi \
  --set prometheus.resources.requests.mem=6Gi

You can disable the public-facing load balancer by providing the annotations to YugabyteDB Anywhere service for disabling that load balancer. Since every cloud provider has different annontations for doing this, refer to the following documentation:
- For Google Cloud, see GKE.
- For Azure, see AKS.
- For AWS, see EKS.
For example, for a GKE version earlier than 1.17, you would run a command similar to the following:
```
helm install yw-test yugabytedb/yugaware -n yb-platform \
--version 2.13.2 \
--set yugaware.service.annotations."cloud\.google\.com\/load-balancer-type"="Internal"
```

Delete the Helm Installation of YugabyteDB Anywhere

To delete the Helm installation, run the following command:

helm uninstall yw-test -n yb-platform
